OIL STOVE.

Application med July 28,

'llhe objectionable features above men-y tioned usually found arethought to be eliminated inthe present invention by the provision of apilot light associated with the principal wick of the burner, the pilotllght remaining burning .all the time. rlhis pilot.

light being once' started there is provided a very easy means ofigniting the main wick upon the mere turning on of the oil supply)Referring to the drawings,

Figure l shows a top plan view of a 'conventional burner in which theinvention has been placed. v

Figure 2 is a vertical elevation of-the burner showing the connection ofthe pilot with the voil supply.

Figure 3 through' the burner showing the construction of the pilot, thefigure being taken along line 3 3 of Figure 2.

Figure d is a fragmentary sectional view of the burner taken on the line4 4 of Figure` 3. 1

Referring more particularly to the dra-wings the burner consists ofacasing l whichis is a fragmentary sectional viewK rovided with aconventional wick 2, the wick eing retained in place by the inner member4l, which is provided with air holes 5.

' Through this wick 2 is placed the pilot, the

construction of which is shown in Figure 3. v"llhe .pilot 3 is retainedin position by the walls 2 which are tightly encased b the shell' of theprincipal burner and by t e inner posi-v tion of the members 9which/members are esi sential to a continuation of the wallsoffthe pipe8, hereinafter mentioned.

'llhe member l0, representing the oil supply pipe is branched as shownat 8, the pipe 8 being bent in the shapeof an elbow, the verticalportion of which carries the wick '3 to the pilot as above described.The burner l is provided with a clamp' 11 which holds the burner inproperppsition.

lin operation the supplyof oil is turned on in the usual fashion andflows upward 'i through the supply pipe 10, a portion of the supply ofoil branching oi" through the memloer 8 and supplying the pilot 3. Inthis connection a column of oil will be trapped in the tube l0 when theoil 'supply valve (not 1927. Serial No. 209,086.

the oil supply valve above mentioned is closed l the burner will becomeextinguished when the oil has burned from the upper or projecting edgeof the wick 2. At this time the oil trapped in the conduit 10 will beconducted to the pilot wick 3 to keep the same lighted. Due to the factthat the upper or projecting edge of the wick 2 is now dry, this wickwill not become ignited. However, upon opening the oil supply valve theoil will be conducted to the upper edge of the wick 2 and ignited by thepilot wick.

The provision of the pilot light assures a steady and continuous llameand permits the lighting of the wick of the burner by means of thisflame withoutthe usual delay in turning the main wick intotheignitingand burning positions, and also the delays incident to thesaturating of this wick with the supply ofv oil, thus avoiding aconsiderable amount f arranged to have communication with a v source ofliquid fuel and constituting a liquid fuel reservoir in which liquidfuel 'is trapped after the burner is extinguished, and a pilot wickchamber in the burner and havinw'communication with the supply conduitwhereby the pilot wick chamber will be supplied with the trapped liquidfuel while the burner is not in operation. i

2. ln a liquid fuel burner pilot, a liquid fuel burner having a wickchamber, a vertical supply conduit leading therefrom to havecommunication with aliquid fuel reservoir and constituting a liquid fuelreservoir in which liquid fuel is trapped after' the burner isextinguished, a tubular member arranged vertically in the wick chamberand having communication with the supply conduit, and a pilot wickarranged in the tubular member and receiving its supply from theverticalY 3. ln a liquid fuel burner pilot, a liquid fuel burner havinga Wick chamber, a' Vertical supply conduit leading therefrom to havecommunication with a liquid fuel reservoir 5 and constituting a liquidfuel auxiliary reservoir in which liquidfuel is trapped after the burneris extinguished, a branch pipe leading wegen from the supply conduitadjacent its upper end and extending through the Wick chamber, and anormally lighted Wick in the branch pipe and adapted to ignite a Wickarranged in the Wick chamber when the upper edge of the latter issaturated with oil.
